Abstract

A device protection apparatus comprising a first sensor (22) for detecting temperature of a refrigerant used for cooling a device including a heat-generation part, a second sensor (21) for detecting temperature of the device, and a controller (10) that applies drive limitation to the device based on a first detected temperature (T1) detected by the first sensor (22) and a second detected temperature (T2) detected by the second sensor (21), wherein the controller (10) calculates a temperature difference between the first detected temperature (T1) and second detected temperature (T2), applies drive limitation to the device when the temperature difference is higher than a predetermined temperature difference threshold value (?T_th), and applies drive limitation to the device when the second detected temperature is higher than a predetermined first temperature threshold value (T_th1).
